Oklahoma City’s 2025 drinking-water report records zero violations
Oklahoma City reported zero drinking-water violations in its annual report covering 2025, according to a city announcement released June 30, 2026.
The city’s 2025 Drinking Water Quality Report, also called the Consumer Confidence Report, says Oklahoma City’s drinking water continued to meet or exceed standards set by the U.S. Environmental Protection Agency and the Oklahoma Department of Environmental Quality.
The finding is the city’s reported compliance result for its municipal drinking-water system during the 2025 reporting year. It is not a report of future plans or a proposed standard.
Annual update for the municipal system
The Consumer Confidence Report is Oklahoma City’s annual update on drinking-water safety, compliance, testing and utility performance. The city’s June 30 announcement identifies the report as its latest Consumer Confidence Report.
For residents and utility customers served by Oklahoma City’s municipal system, the report provides the city’s documented account of the system’s 2025 regulatory performance. The reported number of violations was 0.
The city also said water quality met or exceeded the standards of both the EPA and Oklahoma DEQ. Those are the standards cited in the city’s announcement; the announcement does not describe a change in those standards.
What the zero-violation finding means—and does not establish
The city reported no drinking-water violations. That is a regulatory-compliance finding for the municipal system, based on the city’s announcement.
It should not be read as proof that contaminants were entirely absent from the water. The approved information does not include the full report’s testing tables, contaminant measurements or system-specific sampling details.
Because those underlying details were not provided in the indexed announcement, the available information does not support conclusions about particular contaminants, measurement levels, sampling locations or sampling frequency.
The city’s finding also concerns Oklahoma City’s municipal drinking-water system. It does not establish results for private wells or for water systems outside Oklahoma City.
What happens next
The known action in the available information is the report’s publication on June 30, 2026, for the 2025 reporting year. The city announcement provided no later deadline, follow-up action or additional testing schedule.
Residents seeking details beyond the city’s reported zero violations and standards statement would need the full Consumer Confidence Report, which was not included in the approved source material for this article.
